Level load is heavy load.For heavy load, in corresponding diagram 2 shown in temperature curve P4, within the t2-t1 times, heavy load is not
Can be completely dried, heavy load be in drying process in, then the temperature for loading slowly is reduced, i.e., thermograde sequence be it is negative,
And within the t1-t2 times, due to there are more moisture content in heavy load, then the temperature drop rate of heavy load is born compared in
Carry fast, i.e., the total temperature change value of heavy load is more than total temperature change value of middle load, the total temperature change value of heavy load
Between second temperature difference and the 3rd temperature difference, wherein, second temperature difference and the 3rd temperature difference can be set according to actual conditions.
If thermograde is negative and total temperature change value is more than the 3rd temperature difference, judge that load is that the 5th grade is loaded, its
In, the weight of the weight more than fourth estate load of the 5th grade load, for example, load is loaded for super large.It is negative for super large
Carry, in corresponding diagram 2 shown in temperature curve P5, within the t2-t1 times, super large load will not be completely dried, super large load
In drying process, then the temperature of super large load is slowly reduced, i.e., thermograde sequence is negative, and within the t1-t2 times,
Due to there are more moisture content in super large load, then the temperature drop rate of super large load is fast compared to heavy load, and super large is born
Total temperature change value of total temperature change value more than heavy load is carried, super large loads total temperature change value and is more than the 3rd temperature difference.
